Pregnant and should test? Normal and wait?

My husband and I have been married 2.5 years. We have never used protection - I used BC for one month, but was VERY sick, as I was when I tried as a teen to help with my cycle. For a while I had NO sex drive (mainly because I was uncomfortable with my body), but now it's good. Recently we have both went to the doctor to make sure everything is ok because although we weren't trying or not trying, I haven't got pregnant... Now we are trying! In November my period was 2 days late, but came on, recently it was 2 days late again, but I had a small amount of a dark brown discharge before it came (normal for me!) Now I am currently 3 days late. I've had all the cramps, making me think it is going to come on each day (no discharge though!), but it does not. I would love to be pregnant, but I'm so scared to test and be dissapointed.
